ATTORNEY- PAUL R. BARUFKE, OF WEST HOIBOKEN, NEW JERSEY.

CORN AND CALLUS CUTTER AND TRIMMER.

Application filed October 10, 1917.

To all whom it may concern Be it known that I, PAUL R. BARUFKE, acitizen of the United States, residing at lVest Hoboken, in the countyof Hudson and State of New Jersey, have invented certain new and usefulImprovements in Corn and Callus Cutters and Trimmers, of which thefollowing is a specification.

This invention relates to an improved device for cutting corns andcallus places and the principal object of the invention is to provide aninstrument of the character described so constructed that one jaw orplate can be set upon the foot with the corn or callus place protrudingthrough an opening formed in the plate and the second jaw or plate thenmoved across the first plate to bring the cutting edge of the second jawinto operative engagement with the corn and thus out the corn or callusplace away.

Another object of the invention is to so construct this instrument thatthe cutting edge of the second plate will move across the opening of thefirst plate in the proper manner' for efficient cutting.

Another object of the invention is to provide an instrument of thecharacter described which will be simple in construction and efiicientin operation and to further so construct it that it may be easilysharpened.

This invention is illustrated in the accompanying drawings, whereinFigure 1 is a plan view looking at one side of the instrument, 7

Fig. 2 is a view similar to Fig. 1 looking at the opposite side of theinstrument, the

instrument in this view being closed instead of open as shown in Fig. 1,and

Fig. 3 is a sectional view taken along the line 3-3 of Fig. 2.

In the drawings wherein for the purpose of illustration is shown apreferred embodiment of my invention, the numeral 10 designates a lowerblade and 11' designates an upper blade, both of which are heart-shapedand in the present instance are of substantially the same size. The jawsare pivot-ed together in overlapping relation by a bolt 12 or the like,adjacent their inner ends, and each b-ladeis provided with a handle 13extending longitudinally of the axis of the blade whereby the upperblade may be swung across the lower blade. A substantially ellipticalopening 14 is provided in the lower Specification of Letters Patent.

blade adjacent the forward or pointed end thereof and extendstransversely of the longitudlnal axis of the blade. A second openng 15is provided in the lower blade and 18 arranged adjacent the inner endthereof. The inner edge 16 of this opening forms an acute angle with thelongitudinal axis of the blade 10 and accordingly the opening 15 isadapted for cutting callus placeswhile the opening 14 is particularlyadapted for cutting corns. The outer edges 17 of both openings arebeveled or slightly rounded lnwardly to abut with or catch on the partto be out. ting edges 18 of the heart-shaped plates are provided withcutting edges, the blade 10 having a rounded cutting edge, and it will emanifest that these two cutting edges may intersect and be effectivelyused in severing cuticle's.

From the foregoing, it will be apparent that when the blade 10 is placedupon a foot so that the opening 14 encircles a corn and the edge 17abuts therewith and the handles 13 move together, the cutting edge 18 ofthe blade 11 will move forwardly and outwardly of the opening 14 towardthe far end thereof. Also this cutting edge will move forwardly andoutwardly toward the edge 17 of the opening 15 and in both instances,successive portions of the cutting edge will successively engage andestablish a shear ing action through the corn or callus patch and willnot gouge through the part to be severed.

What is claimed is V 1. A surgical instrument including a pair ofpivotally connected blades having their coacting cutting edges convexedto present a maximum angle therebetween at any relative position of theblades.

2. A surgical instrument including a blade having a plurality ofirregularly shaped openings of diiferent configurations, and a secondblade movable relative to the first and having a cutting edge adapted tointersect the edges of the openings.

3. A surgical instrument comprising a pair of blades pivotally connectedtogether at points adjacent the rear ends thereof and .having convexedges, the convex edge of one blade being provided with a cutting edge,the co-acting blade being provided with a pair of openings, oneof whichis The relative inner convex cut-.
